Edible portions
- flowers in some traditional fritters — not seeds/bark
Absence of a portion from this list means it is not treated as food here — not that every other part is toxic.
Growing
- Climate. 4–8
- Light. Full sun
- Soil. Tough, nitrogen-fixing
- Planting. Thorny, suckering, weedy in places.
- Harvest. Flowers only, if you use them; never bark teas.
Preparation and culinary uses
- Flower fritters in some European traditions
Safety
- Seeds and bark are not food. Flowers are the only commonly cited culinary part.
